In its second Yearbook, the International Association for the History of Transport, Traffic and Mobility (T2M) has brought together 28 scholars from eleven countries on four continents to review recent scholarship on mobility in history.

Besides reviews of research in diverse countries, this edition brings attention to underserved subdisciplines and topics, such as gender and mobility, maritime history, aeromobility, carpooling, and bicycles. This year, the Yearbook also features a retrospective review of John McKay's classic Tramways and Trolleys (1976) in a section that includes an interview with the author and a collection of historical review essays on trams in five countries. True to T2M's interdisciplinary spirit, the review essays go beyond transportation modes and artifacts to include the broader social systems in which mobility figures.
